The module has a 2K-byte dual-port RAM with 1K bytes for inputs and 1K bytes for outputs, which acts a transfer buffer for this purpose. This memory is accessed by both the CPU in the central controller and the microcontroller on the interface module. Data is exchanged between the CPU and the dual-port RAM via the parallel S5 bus on the backplane of the subrack. The microcontroller accepts output data from the buffer previously stored there by the CPU and also transfers input data to the buffer to be scanned there later by the CPU. In a similar manner, the microcontroller also controls data traffic via the serial interface. An EPROM submodule must be plugged into the module if you connect an ET 100U electronic terminator for distributed I/O or ICM 560 individual control modules. The addresses of the input/output modules used and the device configuration are read out of this submodule. The EPROM submodule is programmed using COM ET 100 communications software. No EPROM submodule is required for connecting a 318-3 interface module. You can use the three coding switches on the module to set the diagnostics address (switch 1), the start of the page area (switch 2), the baud rate, the chain watchdog and the time-out mode (switch 3) of the serial interface ( 3.4). EWA 4NEB 812 6051-02a 1-1 System Overview 308-3 Interface Module Figure 1-1 Block Diagram of the 308-3 Interface Module 1.2 Design of the 308-3 Interface Module The 308-3 interface module is a printed-circuit board which can be used both in controllers with block-type modules (e.g. S5-115U) and also controllers with compact modules (e.g. S5-135U). An adapter casing (Order No. 6ES5 491-0L .11) is required for use in controllers with block-type modules. There are two backplane connectors (X1, X2) on the module which mate with the connectors of the parallel S5 bus on the backplane of the mounting rack. Besides the mode selector for switching the module on and off, there is a receptacle on the frontplate for an EPROM submodule (only required if an ET 100U or ICM 560 is connected), as well as a four-pin plug connector into which the interface connector is plugged. Also on the frontplate are a red FAULT LED and two green LEDs which show the operating status of the module. There are three coding switches on the PCB which can be used to make the various settings ( 3.4) 1-2 EWA 4NEB 812 6051-02a 308-3 Interface Module System Overview 1 Receptacle for memory submodule 2 Mode selector 3 Red FAULT LED 4 Green LEDs (interface display) aaaaaa aaaaaa 5 Receptacle for the serial interfaces (2 chains via socket connectors) X1/X2 X3/X9/X11 X7 X8 S1 S2 S3 48-way backplane connector Jumpers for page addressing 4-way plug connector for serial interfaces Memory submodule "Diagnostics address" switch "Page number" switch Switch for "Baud rate", QVZ and "Interface watchdog" X 13 X14 PIN 1/2 X14 PIN 2/3 Jumper inserted* Jumper for PESP evaluation CPKLA/ X2. z18 jumper (if the 308-3 interface module is plugged into a central controller) * CPKLA/ X2. z14 jumper (if the 308-3 interface module is plugged into an expansion unit) * Figure 1-2 EWA 4NEB 812 6051-02a On delivery Design of the 308-3 Interface Module 1-3 System Overview 1.3 308-3 Interface Module Device Configuration There is a wide range of device configurations possible thanks to the large number of nodes which you can operate simultaneously on both interface chains of the 308-3 interface module.

The following pages contain information on the various requirements to be met when selecting and connecting the transmission cable. EWA 4NEB 812 6051-02a 2-1 Hardware Installation 2.1 308-3 Interface Module Slots for the 308-3 Interface Module The 308-3 interface module can be plugged into the S5-115U, S5-135U, S5-150U and S5-155U programmable contollers, as well as the EU 185U und EU 186U expansion units. Figure 2-1 shows the slots which can be used. 1) 2) 3) 4) 5) The CP and IM 308-3 cannot be operated simultaneously when plugged into these slots! The 308-3 interface module can usually only be plugged into the EU 185U and EU 186U expansion units if the expansion units and the central controller are interconnected via the IM 304/314 pair. If the IM 308-3 is to be operated with page mode in the expansion unit, jumper X13 must be removed. Only subracks CR 700-2, CR 700-3 and CR 700-0LB.. can be used with the S5-115U. In addition, an adapter casing is required for adding the 308-3 interface module. Two 308-3 interface modules in one adapter casing can be plugged into slot 6 of subrack CR 700-3 or slot 3 of CR 700-0LB..

Transmission must be tested at a rate of 375,000 baud and must be free of noise. All noise-generating parts of the system must be in operation during this test. Then set the baud rates as follows: - up to 250 m: max. 62,500 bps - up to 500 m: 31,250 bps Longer cables are not permissible! If you comply with these requirements, fault-free operation should result, but cannot be guaranteed. EWA 4NEB 812 6051-02a 2-7 Hardware Installation 308-3 Interface Module 2.3.3 Connecting the Transmission Cable Signal Line Connections The 308-3 interface module is supplied with the interface connector for the transmission cable. The screw-type connections are suitable for stranded conductors with a cross-section of between 0.5 mm2 (20 AWG) and 1.5 mm2 (15 AWG). Core end sleeves are recommended. A connection schematic is shown below ( Figure 2-2) Chain 1 1 2 3 4 S S-N* S S-N* Chain 2 * S-N = Negated signal Figure 2-2 Connecting the Transmission Cable If you loop the transmission cable through from one node (318 interface module or ICM 560) to the other, terminate the incoming and outgoing transmission cables in parallel on the front connector. If you should mistakenly cross the conductors of one or more interface modules, it will be impossible to reference these modules. The 308-3 interface module will not detect an interface error. 2-8 EWA 4NEB 812 6051-02a 308-3 Interface Module Hardware Installation Terminating Resistor Each interface chain must be terminated at the last node with a standard 120 ohm, 0.25 W carbon-layer resistor (supplied with the 308-3 interface module). Slide the insulation sleeve (also supplied) over the resistor to prevent unintentional contact with the connecting wires. Then simply clamp the resistor between terminals 3 and 4 on the interface connector of the last node. Make sure that good contact is made. If possible, press the resistance wires together with the stranded transmission conductor into the same core end sleeves. Connecting the Shielding You must ground the transmission cable shield as close as possible to the expansion unit using a ground clamp, or at the point where the cable enters the cabinet with a shield bar. Continue the shielding right up to the interface connector without grounding it again.

Each I/O area encompasses 256 bytes of input data and 256 bytes of output data. Exceptions: One byte per 308-3 interface module is required as a diagnostics address in the P area. The diagnostics address in initial page area Qn is required for the purpose of page addressing. The address areas of all ET 100Us and ICM 560s are assigned using COM ET 100U communications software and stored in an EPROM submodule. The EPROM submodule is plugged into the 308-3 interface module after being programmed. Neither an address list nor an EPROM submodule are required for addressing the I/O area in expansion units with the 318-3 interface module. 2-11 308-3 Interface Module aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa Hardware Installation aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa Note: * Address 255 is reserved for page selection during page addressing and cannot be used for input/output modules in the Q area. * Make sure that the Q area cannot be directly referenced in the same central controller (double addressing) in the case of page addressing. * The diagnostics address set cannot be used for input/output modules. * There must be no I/O module having the same address in the central controller if the 308-3 interface module references address areas Q, IM3 or IM4 (double addressing). * The S5-115U recognizes the following address area: - CPU 941 ... 944 address area P - CPU 945 address areas P and Q. 2.5 Page Addressing (Duplication of the Q Area) Page addressing is based on the duplication of the Q area. For page addressing, this area must be present in your programmable controller. This is the case in the S5-135U, S5-150U and S5-155U. In the S5-115U, CPU 941 ... 944 have only the P area. You can convert any 308-3 interface module to page addressing by changing jumpers X3, X9 and X11 on the module ( 3.4.5). This allows you to process up to 4 x 255 bytes of input data and 4 x 255 bytes of output data in the Q area of each 308-3 interface module. Each 308-3 interface module in the central controller can also be converted to another initial page area. A total of 64 initial page areas are available. Page addressing thus frees 4 x 64 x 255 bytes for input data and 4 x 64 x 255 bytes for output data. Use linear addressing first. Up to 1K bytes (4 x 256 bytes) of address area are available to you for linear addressing, depending on your programmable controller. Duplication of the Q area is only to be recommended if this address area is insufficient. 2-12 EWA 4NEB 812 6051-02a 308-3 Interface Module Hardware Installation Page areas * I/Q areas ** IM 4 IM 3 aaaaaaaaaaaaaa aaaaaaaaaaaaaa aaaaaaaaaaaaaa aaaaaaaaaaaaaa aaaaaaaaaaaaaa aaaaaaaaaaaaaa aaaaaaaaaaaaaa 254 Qn+3 Qn+2 252 Qn+1 Q 0 P Qn 0 * ** 4 8 12 16 20 Initial page area Qn * Must be set on the 308-3 interface module Must be set on the 318-3 interface module, or must be programmed for the ET 100U and ICM 560 using COM ET 100 communications software Figure 2-4 Graphical Representation of Page Addressing EWA 4NEB 812 6051-02a 2-13 aaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaaaaaaaa 3 Start-Up 3.1 Start-Up of the Interface Module . . . . . . . . . . . . . . . . . 3 - 1 3.2 Serial Interface . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 3. - 2 3.3 Data Exchange . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 3. - 2 3.4 3.4.1 3.4.2 3.4.3 3.4.4 3.4.5 3.4.6 Default Settings on the Module . . . . . . . . . . . . . . . . . . . 3 Chain Watchdog . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 3.

All units connected are initialized during configuration. The power supply to these units must therefore be on. The configuration run lasts approximately 5 to 20 seconds, during which time the red LED flashes with a frequency which depends on the baud rate set. The 308-3 interface module will start up properly, even if the CPU is in the STOP mode. If the red LED flashes for longer than 20 seconds, there is either a fault in the module (RAM or ROM error) or the EPROM submodule has been wrongly programmed (check with COM ET 100U) aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaa Note: The CPU switches must not be operated during the configuration run. Mode Selector in OFF Position * * * When the mode selector on the frontplate is in the OFF position, the units connected to the serial interface can no longer be referenced and assume the wait status. The CPU generates a BASP signal (command output disable). The CPU receives diagnostics byte 0. Bit F6 in this byte means "Distributed I/O not ready". If QVZ (time-out) mode is active ( 3.4.3), a time-out will be recognized by the CPU. EWA 4NEB 812 6051-02a 3-1 Start-Up 3.2 308-3 Interface Module Serial Interface The serial interface is floating and is similar to the EIA (Electronic Industries Association) RS 485 standard. Both interface chains are at the same potential and operate in parallel. You must activate the relevant interface when the transmission cable is connected and the terminating resistor is connected to the end of the chain ( 3.4.1). The relevant green LED will then light up. If one of the interface chains is not used, the relevant interface must be switched off . The relevant green LED will then remain dark. If you activate an unused interface, a time-out will result, irrespective of the position of the time-out switch (QVZ). 3.3 Data Exchange I/O data is exchanged in half-duplex mode on the master-slave principle between the central controller and the expansion units, the ET 100U or the ICM 560 via a serial transmission link. Both interfaces together can take a maximum of 64 nodes, of which only 62 may be ET 100Us or ICM 560s. A terminating resistor (120 ohms, 0.25 W) is required at the end of each chain. Using COM ET 100U communications software, you must program the number of input and output bytes and their initial addresses for all ET 100Us and ICM 560s connected and store this information in the EPROM submodule. As is usual with the input/output modules of the U range, the individual addresses of the modules are set in the expansion units. 3-2 EWA 4NEB 812 6051-02a 308-3 Interface Module Start-Up Data Transmission Security aaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaa aaaaaaaaaaaaaaaaaa aaaaaaaaa You can monitor the data transmitted by inserting one or two check bytes at intervals of up to 18 data blocks with cyclical BCH code (Hamming code). Noise immunity can be improved for slower data transmission rates by using a filter. Baud rate 375,000 bps 187,500 bps 62,500 bps 31,250 bps Number of check bytes Filter 1 2 2 2 no no yes yes After a fault has been detected, the message is repeated twice before an error message appears. Parasitic signals can cause a unit to switch off automatically (the ICM 560 switches to manual mode). However, the system prevents erroneous setting of outputs. After a cold restart following a fault, the 308-3 interface module executes a reconfiguration run. Please note the following during configuration: - If you expect severe interference, you should use one of the two lowest baud rates. - If you have to select a high baud rate for reasons of speed, please pay careful attention to the guidelines for connecting and laying transmission cables. 3.4 Default Settings on the Module Before putting the module into service, you must use the three coding switches to set the diagnostics address (switch S1), the initial page area (switch S2) and the baud rate, chain monitoring facility and QVZ mode of the serial interface (switch 3). Use a ballpoint pen or similar pointed object, but not a pencil, to set the switch blocks. In the following setting examples, a pressed switch is represented by: *. Switch S3.4 is not assigned. EWA 4NEB 812 6051-02a 3-3 Start-Up 3.4.1 308-3 Interface Module Chain Watchdog The chain watchdog of both serial interfaces is set using switches S3.5 or S3.6. When activated (S3.5 or S3.6 at OFF), the interface chain watchdog checks whether the transmission cable connected has a terminating resistor of 120 ohms. The relevant green LED lights up. If one of the interface chains is not in use, you must set the relevant switch to ON. The relevant green LED then remains off. If you activate an unused interface, this will always result in a time-out, irrespective of the position of the QVZ mode switch.

However, you must take the required response speed of the process into account. The response speed drops with the baud rate. Set the same baud rate for all nodes as that set for the 308-3 interface module. The baud rate of the transmission line is set using switches S3.1 and S3.2.

To operate the module and the relevant I/O modules under normal SIMATIC S5 conditions (time-out when module is unplugged, etc.), QVZ mode must be activated (switch S3.3 in the OFF position). The 308-3 interface module transmits the READY (RDY) signal for all those modules which were plugged in during configuration and which were assigned addresses in the EPROM submodule using COM ET 100U communications software. However, it may be useful to switch off QVZ mode during the start-up procedure of your system (switch S3.3 to ON), in order to test the system section by section, for example. Unplugging a module will not then result in a time-out. It is necessasry to program the relevant organization block (QVZ-OB) to prevent the CPU from stopping in the event of a time-out. You will find more details in your programmable controller manual.

If the 308-3 interface module does not generate a READY Signal, it will not transfer any data to the S5 bus and the CPU will not recognize a time-out. If you want the CPU to continue to run after a time-out, you must take the CPU's response in this situation into account (see the relevant PC manual). 3-7 Start-Up 3.4.4 308-3 Interface Module Diagnostics Address aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaa A diagnostics byte is stored in the 308-3 interface module for each node ( Chap. 4).

You can set the initial page area for all 309-3 interface modules in steps of four using switch S2.

However, make sure that no double addresses occur within the same page area. Your selection of an initial page area for a 308-3 interface module will establish the four page areas Qn, Qn+1, Qn+2, and Qn+3 for that module. For example, if you select initial page area 16, Qn Qn+1 Qn+2 Qn+3 3-12 will be called with parameter will be called with parameter will be called with parameter will be called with parameter 16 17 18 19 EWA 4NEB 812 6051-02a 308-3 Interface Module Start-Up In this chapter, under the heading "Page Selection", you will learn which STEP 5 operations you need to access a page area. You can have 255 bytes of input data and 255 bytes of output data in each page area. You must preset a given node according to the page area within which you wish to communicate with that node. This area is set in the 318-3 interface module using Switch S2, and in the ET 100U and ICM 560 using COM ET 100 communications software. Setting is the same as for areas P, Q, IM3 und IM4 in the case of normal addressing. For this purpose: Qn Qn+1 Qn+2 Qn+3 corresponds to area corresponds to area corresponds to area corresponds to area P Q IM 3 IM 4 Setting the Initial Page Area Set the selected initial page area at Switch S2 by pressing the switch with the relevant value down into the ON position.

Figure 3-6 Typical Initial Page Area Setting EWA 4NEB 812 6051-02a 3-13 Start-Up 308-3 Interface Module Page Selection Address 255 (F1FFH) is reserved for page selection in the Q area. The following operations are used for page selection: L T KB QB n 255 where n= 0 to 255 (desired page area) This selects page area n. You can now use any of the load and transfer operations of the Q area (byte and word operations).Your page selection applies until you select a new area. Data exchange then takes place in this new page area. 3.5 Transmission Time of the Serial Transmission Link Specific transmission times are required in order to update the contents of the buffer (dual-port RAM) of the 308-3 interface module. These transmission times depend on the individual module configuration and the baud rate set. You will find the relevant values in the following tables.

Each address gap generates new messages with additional address header and control characters. This increases the transmission time tEU. aaaaaaaaaaaa aaaaaaaaaaaa aaaaaaaaaaaa aaaaaaaaaaaa aaaaaaaaaaaa aaaaaaaaaaaa aaaaaaaaaaaa aaaaaaaaaaaa aaaaaaaaaaaa aaaaaaaaaaaa aaaaaaaaaaaa aaaaaaaaaaaa aaaaaaaaaaaa aaaaaaaaaaaa aaaaaaaaaaaa aaaaaaaaaaaa aaaaaaaaaaaa aaaaaaaaaaaa aaaaaaaaaaaa aaaaaaaaaaaa aaaaaaaaaaaa aaaaaaaaaaaa aaaaaaaaaaaa aaaaaaaaaaaa aaaaaaaaaaaa aaaaaaaaaaaa aaaaaaaaaaaa aaaaaaaaaaaa aaaaaaaaaaaa aaaaaaaaaaaa aaaaaaaaaaaa aaaaaaaaaaaa aaaaaaaaaaaa aaaaaaaaaaaa aaaaaaaaaaaa aaaaaaaaaaaa aaaaaaaaaaaa aaaaaaaaaaaa aaaaaaaaaaaa aaaaaaaaaaaa aaaaaaaaaaaa aaaaaaaaaaaa aaaaaaaaaaaa aaaaaaaaaaaa aaaaaaaaaaaa aaaaaaaaaaaa Table 3-4 Transmission time tEU Baud rate 375,000 bps 187,500 bps 62,500 bps 31,250 bps Transmission time tEU c x 3.0 ms/EU + d x 0.09 ms/byte c x 4.5 ms/EU + d x 0.12 ms/byte c x 8.5 ms/EU + b x 0.25 ms/byte c x 13.0 ms/EU + b x 0.40 ms/byte Parameters c and d are defined as follows: c=Total number of expansion units connected to the 308-3 interface module by the 318-3 interface module (both chains) d=Sum of all input and output bytes of all expansion units.

At the end of this time, the status information of, for example, an input in the buffer (dual-port RAM) of the 308-3 interface module is updated. The time required for data transmission on the I/O bus of the modules connected must be taken into account as well as the transmission time of the serial transmission link: * * aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaaaaaa aaaa * See Manual 6ES5 998-2ET11 for the transmsission times of the ET 100U I/O bus. 1 ms per byte of input/output data is a typical value. In the expansion unit, data transmission to the I/O modules is via the parallel S5 bus. The time required for this is negligible and already accounted for in tEU. The internal response times for the ICM 560 individual control module are given in Manual 6ES5 998-0KC11, but these times are already accounted for in tICM. aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaaaaaaa aaaaa Note: From version 308-3UA12 upwards, the 308-3 interface module has a minimum cycle time which depends on the baud rate set.

This chapter is designed to help you to detect and remove faults. 4.1 Accessing the Diagnostics Byte A diagnostics byte is stored for every node in the 308-3 interface module plugged into the central controller . The diagnostics byte for ET 100U electronic terminators for distributed I/O and for ICM 560 individual control modules is stored under the number of the relevant unit (Nos. 1 to 63). The diagnostics byte for expansion units and group messages is stored under No. 0. The diagnostics bytes of all nodes are stored in the buffer (dual-port RAM) of the 308-3 interface module, and can be referenced by load and transfer operations. You must set the address of the diagnostics byte (diagnostics address) on the module ( 3.4.4). Accessing the diagnostics byte: L KB i T L PY PY m m i = 0 for expansion units i = 1 to 63 for ET 100Us and ICM 560 m = 128 to 255 (diagnostics address) If you use the STUDOS (S0; S1) operating system in the programmer (PG 675, earlier version), you must write the T PB m and L PB m operations in place of the T PY m and L PY m operations. If you are using page addressing for the 308-3 interface module, you must note that the diagnostics byte can only be read in the initial page area Qn (n= 0, 4, 8, 12 to 252). Access is then as follows: L T KB QB n 255 Select initial page area L KB i T L QB QB m m i = 0 for expansion units i = 1 to 63 for ET 100U and ICM 560 m = 0 to 254 (diagnostics address) EWA 4NEB 812 6051-02a 4-1 Error Diagnostics 308-3 Interface Module This means you can respond quickly to specific error states by making bit comparisons. To avoid a time-out being activated by an error and causing the CPU to stop ( 3.4.3), it is necessary to program the relevant organization block. Note: * * * 4.2 Diagnostics bits can occur in combinations. Error information is scanned cyclically. This can mean that errors which appear briefly are not captured and the relevant diagnostics bits are not set. Error messages are not stored. Exception: Diagnostics bits which existed before the generation of FO remain set. Diagnostics Byte for Expansion Units and Group Messages Diagnostics byte No. 0 contains both group messages concerning all I/O modules and the diagnostics bits for expansion units. You can tell from the bit pattern whether an error has occurred and, if so, which error. The relevant bit then has signal state "1".
